There has been a continual debate on which programming language/s to learn, to use. As the latest TIOBE Programming Community Index for August 2021 indicates – C (13%), Python (12%), C++ (7%), Java (10%), and C#(5%) together control nearly half the programming activities worldwide. Further, C Programming Language Family (C, C++, C#, Objective C etc.) dominate more than 25% of activities. Hence, learning C++ is important as one learns about the entire family, about Object-Oriented Programming and gets a solid foundation to also migrate to Java and Python as needed. C++ is the mother of most general purpose of languages. It is multi-paradigm encompassing procedural, object-oriented, generic, and even functional programming. C++ has primarily been the systems language till C++03 which punches efficiency of the code with the efficacy of OOP. Then, why should I learn it if my primary focus is on applications? This is where the recent updates of C++, namely, C++11 and several later offer excellent depths and flexibility for C++ that no language can match. These extensions attempt to alleviate some of the long-standing shortcomings for C++ including porous resource management, error-prone pointer handling, expression semantics, and better readability. The present course builds up on the knowledge of C programming and basic data structure (array, list, stack, queue etc.) to create a strong familiarity with C++98 / C++03. Besides the constructs, syntax and semantics of C++ (over C), we also focus on various idioms of C++ and attempt to go to depth with every C++ feature justifying and illustrating them with several examples and assignment problems. On the way, we illustrate various OOP concepts. The course also covers important advances in C++11 and later released features.

Programming Assignment :

W5_Programming_Qs-1 :

class DD : public B, public D{ //LINE-1

    int d;
    public:
        DD(int x) : B(x+x), D(x+x+x), d(x){} //LINE-2

        void show(){
            cout << d << ", " << b1 << ", " << b2;
        }
};

W5_Programming_Qs-2 :

#include<iostream>
using namespace std;
class Student{
    string n;
    string s;
    int m;
    protected:
        Student(string _n, string _s, int _m) : n(_n), s(_s), m(_m) {}
    public:
        friend void studDetails(const Student&); //LINE-1
};
class Bengali : public Student{
    public:
        Bengali(string n, int m) : Student(n,"Bengali",m){} //LINE-2
};
class English : public Student{
    public:
        English(string n, int m) : Student(n,"English",m){} //LINE-3
};

W5_Programming_Qs-3 :

class Sphere : public Area, public Volume{
    int r;
    public:
        Sphere(int _r) : r(_r){ }
        double getArea(){ return Area::getVal(r); } //LINE-1
        double getPerimeter(){ return Volume::getVal(r); } //LINE-2
};

CRITERIA TO GET A CERTIFICATE :

1. Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
2. Exam score = 75% of the proctored certification exam score out of 100
3. Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met,you will not get the certificate even if the Final score >= 40/100.
